- Multigrid with Coefficients
We would like to understand the scale dependence of parameters when the scales are not so much physical as numerical, say in a multigrid iteration. I think what we want is closer to naive renomalization, as practiced by Ken Wilson, also called functional renormalization. His essay about problems with many scales is also worth reading.
I think the main question is "What auxiliary equations should be used to update params at each scale?" (integrating out, beta function)
